Redhat6.1 crashed

[Hong F Du]

Hi All,

I was working my problem of "cannot change permission on mountable drive" (see previous mails), and accidentally killing a process.

When I reboot, the boot processing went through checking root file system, /dev/hda10 clean check, setting up ISA PNP devices, and after Remounting root file system in read-write mode it stopped there and couldn't go further. I used a floppy to boot. It did the same things and stopped there.

I don't know what to do to rescue my system. I cannot any file under linux file system to go the log files. Please tell me what to do. Any suggestion will greatly appreciated.

Use your RedHat bootdisk with kernels AND file system on them then
mount your /dev/hda10 (did I see that right? 10??) into a mounting
point (I do not remember whether you need to mount in order to do file
system check, you may not need to) and maybe clean up your rc.d to
boot. Run minimum amount of devices as you need (hdparm, gpm, etc..)
and if you run X, just make it not to start X and then try rebooting
the system.. Always, backup backup backup!!.. :)

Good luck!!!!

The only Redhat bootdisk that I have is the one created when I first time installed
Redhat. Is the one you are saying? I tried that one already, it stopped booting on
the same step while booting. How do I mount /dev/hda10? I cannot see any file under
the original linux system, how do I clean up my rc.d? What else can I do?
Help........please.

I greatly appreciate your detail instructions.

My bootdisk doesn't have root directory on it, I think. It automatically went to
/dev/hda10 and mounted root. It passed the clean check for /dev/hda10. It prompted
Remounting root filesystem in read-write mode [OK] too. Then it tried to do next
step and stop there.

I also tried to use "rescue" option when booting from bootdisk. It asked me for a
root disk which I don't have and I am stuck again. Am I dead here? : (
